7 Claims.

My invention relates to spools, and, more particularly to spools madefrom pasteboard; and, it has for an object to provide a spool light inweight, strong and highly efiicient for the purpose intended.

A further object of the invention is to provide a spool wherein thetubular body portion and the flanges are rigidly connected.

A still further object of the invention is the provision of a spoolwhich possesses advantages in points of simplicity and efiiciency, and,at the same time proves itself comparatively inexpensive in cost ofmanufacture.

With the above and other objects in view, the invention consists in thenovel features of construction, arrangement and combination of partshereinafter more fully described and finally pointed out in the claimshereto appended.

Referring to the accompanying drawing forming a part of thisspecification wherein like characters of reference denote similar partsthroughout the several views:

Fig. 1 is a view partly in side elevation and partly in sectionalelevation of a pasteboard spool and showing a facing ring member at eachendthereof before it has been rolled into final position.

Fig. 2 is a view partly in side elevation and partly in sectionalelevation of the spool showing the facing devices rolled into finalposition and one of the pasteboard flanges in contact with one of theend facing devices, but not fixed thereto.

Fig. 31s a view of the spool partly in side elevation and partly insectional elevation showing the flanges secured to the spool.

Fig. 4 is a sectional elevation of one of the spool flange retainingrings.

Fig. 5 is a plan view of one of the pasteboard flanges for the spool.

Referring to the drawing, 1 designates a tubu lar member, preferablymade from spirally laminated pasteboard, although not necessarily limrited thereto, to the ends of which are connected 0 wall 3 terminating atits one end in a right angular flange 4, as shown at the left side ofFig. 1, before it is finally fixed to theiend of the Y tube.

The ring wall 3 of the facing device is receivable within the end of thetube and snugly fits be securely connected to each end of the tube 1,are provided with a central opening 5 so that the spool can be mountedupon a suitable spindle 6, as illustrated in Fig. 3.

The pasteboard flanges 2 are connected to the ends of the tube 1 incontact with the end face of the facing rings, as clearly shown in Fig.3. In Fig. 2, I have shown one of the flanges 2 in position before it isconnected to the end of the tube, as shown in Fig. 3.

The means for securely locking the flanges to the end of the tube 1comprises a metallic locking device, or members embodying a ringlikewall '7 and a right angular flange 8 formed at one end of the ringlikewall 7, as shown in detail in Fig. 5.

After the flange 2 has been applied or mounted in contact with one ofthe facing devices, a locking device is applied by forcing the ringlikewall 7 thereof through the opening 5 of the flange and into the tube 1so that the outer face of the ringlike wall 3 of the locking device isin frictional contact with the inner face of the ringlike wall 3 of thefacing device.

After the locking device has been thus applied, the ringlike wall of thelocking device is rolled or otherwise suitably pressed outwardly intotight frictional contact with the wall of the facing ring and the flange8 of the locking device is brought into tight frictional contact withthe outer face of the pasteboard flange 2, thereby securely holding thepasteboard flange in locked relation with the end of the tube.

From the foregoing description, it is evident that I provide a light,strong and comparatively inexpensive spool upon which wire, ribbon orany other suitable material may be wound.

The many advantages of the herein described invention will readilysuggest themselves to those skilled in the art to which it appertains.

From the foregoing description, it is evident that a simple device forthis purpose has been disclosed, but it is to be understood that I do110 not desire to restrict, or limit myself to the very details of theconstruction shown and described, which is merely illustrative, it beingobvious that changes, not involving the exercise of invention, may bemade without conflicting or departing from the spirit of the inventionwithinthe scope of the appended claims.

What I claim is: a a

1. As an article of manufacture, a spool comprising a cylindrical spoolbody, metallic facing devices each having a flange rolled into lockedengagement with the outer face of the tube at each end thereof, apasteboard flange in contact with the end face of each facing device anda locking device having a portion thereof passing through a centralopening in each flange and pressed into frictional contact with the tubefacing devices and having a flange for pressed engagement with the outerface of the flange.

2. As an article of manufacture, a spool comprising a cylindrical spoolbody, metallic facing means applied to the ends of the tube, a flangehaving a central opening mounted upon the end face of each facing meansand metallic locking means having a ring like wall adapted to passthrough the central opening of each pasteboard flange and provided atits outer end with a flange, the ringlike wall of said locking devicebeing pressed outwardly into frictional contact with the facing meanswithin the tube and the flange of the locking device being pressed intofrictional contact with the outer face of the pasteboard flange at eachend of the tube to prevent displacement of the pasteboard flanges.

3. In a spool construction, a tubular body. a ring like device having aperipheral edge fixed to each end of the tubular body by rolling thedevice into engagement with the inner end and outer faces of the tubularbody to provide a rolled facing for each end of the tubular body, a diskhaving a central opening mounted upon the rolled facing at each end ofthe tubular body and a pair of devices each having a pasteboard flangein contact with the outer faces of the disk and said devices beingsecured to the tube facings by friction contact therewith within thetube.

4. In a spool construction, a tubular paper body, a metallic facing ringmember secured to each end of the tubular body and engaging the inner,outer and end faces thereof, a flanged ring carried at each end of thetubular body and in frictional contact with the inner faces of thefacing ring members and a disk for each end of the tubular body, saiddisks each having a central opening for receiving the flanged rings tomount said disks between the metallic facing ring members and theflange's of the rings.

5. In a spool construction, a tubular paper body, a metallic facing ringmember secured to each end of the tubular body and engaging the inner,outer and end faces thereof, a flanged ring carried at each end of thetubular body and in frictional contact with the inner faces of thefacing ring members and a disk for each end of the tubular body, saiddisks each having a central opening for receiving the flanged rings tomount said disks so that the facing ring members will prevent inwarddisplacement of the disks and the flanges of said flanged rings preventoutward displacement of the disks.

6. In a spool construction, in combination, a cylindrical tubular body,flanged metallic facing rings applied by frictional contact to the endsof the tubular body, a flanged metallic locking ring applied to thefacing rings by frictional contact within the tube and a disk mountedupon each flanged locking ring between the flange thereof and the tubefacingrings and in facial contact therewith.

7. In a spool construction, in combination, a cylindrical tubular body,metallic facing devices applied to the ends of the tube by frictionalcontact therewith, metallic locking devices applied to the metallicfacing devices within the tube by frictional contact and a pasteboardspool flange carried by each metallic locking device.
